my fans still not coming on i got brn to ignition,orn battery,drk grn/wht to drk grn off of lt1 c100 and gry to drk bluoff of lt1 c100. if i jump either wire with positive when car is off they come on. and if i do the same on negitive with the car on they come on so whats the deal? can i or does any one have theres grounded to come on when car is turned on? i'v checked the wiring over and over i cant find anything dissconnected either.

 

I had them hardwired to come on when the key was on for almost a year. Its no problem to do it that way, I just wanted to get everything working the way it was supposed to.

 

Yea, one thing you can do is just splice into a wire that gets power when the key is on and pick up a power distribution block and get a lead and mount it there, then wire your fans and whatever else you want on when you turn the key to that extra power distribution. I think this is what im gonna do to clean up the engine bay.

 

Best way to get that to work is to play around with the relay input/output wires for your fans.

See if the main power is going to the relay, check if the relay is working and see if the relay switching power is there when the fans are supposed to come on.

 

I realize you'd like answers to your specific problem but without being right in front of the car-not too many peole can help directly....we can all give you alternatives though, which may not be what you want. I used two SPDT Bosch type relays you can usually find in the foglight section of a local autoparts store. I did this after I realized that the fans actually ran just a bit faster this way then by going via the OEM relay. This is most likely due to me getting direct battery voltage to the fans. Good luck though.

 

I went and grounded the wires from the fan relays so they come on when i turn it on. I took it out for a drive today and my power steering pump line blow off but i drove on any way it did pretty good but it was with open header real nice sound I have to get some kind of connecters for the power steering lines. how high does the temp have to be? mine was under 220 is that good for that engine or not? any info please. and thanks for all the info guys could not have done this with you
pasky don't know if i told you but i bought the vats by pass and it works great.

 

220 is normal stock temperature, if I recall correctly the secondary fan doesn't kick on ti'll 230.

 

good point. the stock fan settings are way too high. If you have access to Tunercat or LT1Edit, turn the temps down and I bet it will solve your problem.

 

where can i get these programs? i have the tan off of lt1 c105 going to orange wire on aldl is that how you guys connected yours and also the ground. and those this program need any kind of plug?

 

Need a cable, I forgot the link I had to order them for 40 bucks. Its a ALDL to serial cable, akmcables.com charges like 90 bucks, I wish I had a link to the $40 dollar one. Me or texas can hook you up with the definition file for tuner cat.

 

thanks man that will work. pasky where did you get your power steering line?
